We have a radio comms site with multiple equipment. Originally the site was set up with a positive ground at the rectifiers. We have some new equipment that is powered from the rectifier shelf, that will not work well with a positive ground. We were thinking of changing one of the rectifiers to a negative ground. My question is would this cause a problem?
In my mind, having a positive ground and negative ground connected to the same main site ground just seems wrong, but is it? Would there really be a conflict here or not?
All voltage is DC, with exception of input power to rectifier shelves (120AC).
